In this paper, we consider two kinds of energy constraints when the output state is a coherent state. Conventional constraint is a constraint on the total energy per a single communication mode. This paper proposes another energy constraints, which is a constraint on the total energy during a fixed period. The first setting can be easily dealt with by using the conventional capacity formula. This...
Without any control mechanism, a wireless ad-hoc network is easily congested and the perceived quality of applications considerably deteriorates. Therefore, we need QoS control mechanisms to accommodate real-time multimedia application such as video conferencing, VoIP (voice over IP), and remote monitoring while satisfying application QoS requirements. In this paper, we propose a new routing mechanism...
